| 摘 要： | 混响室作为一种经济有效的新型电磁兼容检测设备，近年来倍受人们的关注。在混响室的设计过程中，材料的选择是其中的关键环节之一。通过仿真计算，从电场强度大小和电场均匀性两个方面研究了四种不同电导率材料对混响室场性能的影响。数据结果表明，随着材料电导率的升高，混响室内电场强度的各分量最大值和电场强度平均值均明显提高，并且材料电导率的变化不改变室内电场的分布情况。从电场均匀性方面来看，四种不同电导率材料的混响室，其电场均匀性均满足标准IEC61000-4-21的要求。

| Abstract: | In this paper, effects of four materials with different conductivity on field performance of rever- beration chamber including field strength and field uniformity are studied by computer simulation technol- ogy. The results show that with the conductivity of material improving, the maxima of field components and the average field strength are enhanced remarkably. And the material conductivity does not change the distribution of the electric field. From the point of field uniformity, the field uniformity of reverberation chamber with each material can satisfy the requirement of Standard IEC61000-4-21. |
